Amazon pushes out 6.2.1 Kindle Fire update
Contributors on the XDA-Developers forums are reporting that Amazon's just-published 6.2.1 software update to the Kindle Fire e-book reader breaks hacks again. The patch remove roots as well as ROMs other than the Amazon-issued code from the devices, though this time around, it's not yet possible to re-root the device using known exploits as the SuperOneClick utility is blocked mid-install. The update is difficult to stop, as Amazon automatically pushes out updates without any user interaction or permission required.
Some developers believe they can block the automatic update by renaming the folder and therefore redirecting where the update gets installed. Others believe their CyanogenMod 7-modified Fires are safe from the update.
The update is otherwise said to offer some performance bumps including smoother scrolling and password protection for the Wi-Fi radio. Users can also now remove recently used items from the home screen carousel.
